Hertel GH072032 Square End Mill 1/2 in 2 Flute Hss Tin

Product Description

The HERTEL GH072032 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M7 high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in ferrous and non-ferrous materials. The mill features a 1/2 inch cutting diameter, a 3 inch length of cut, and a 5 inch overall length, placing it in the extra long category. The 42-degree helix angle promotes efficient chip evacuation and smooth cutting action. Installed by machinists and tool-and-die professionals, this end mill is suited for CNC machining centers and manual milling machines alike.

This end mill is intended for slotting, profiling, and peripheral milling applications where extended reach is required. The extra long flute length makes it well suited for deep pocket milling and step milling operations where a standard-length tool cannot reach the workpiece. The right-hand cutting and right-hand flute direction are consistent with conventional spindle configurations on most vertical and horizontal milling setups. The 1/2 inch shank diameter fits standard ER and end mill holders designed for that bore size.

Key Features

• M7 high speed steel construction for toughness in interrupted cuts and general milling
• Titanium nitride (TiN) coating reduces wear and extends tool life compared to uncoated HSS
• 42-degree helix angle promotes efficient chip flow and reduces cutting forces
• Extra long 3 inch length of cut for deep pocket and extended-reach applications
• Center-cutting design allows plunge entry directly into the workpiece
• Right-hand cut and right-hand spiral flute direction for use in standard spindle configurations

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any milling setup accepting a 1/2 inch shank end mill, including ER32, ER40, and similarly sized end mill holders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle and holder are clean and free of chips before seating the shank. Torque the set screw or collet nut to the holder specification only. Verify tool projection and runout with a dial indicator before initiating a cut.
